Subject: [dpdk-dev] [PATCH 3/3] net/iavf: set pointer to NULL after free
Date: Tue, 15 Feb 2022 18:25:03 +0800	[thread overview]
Message-ID: <bc4ae5b647546d31f83b6eca6f5be390c0cd38ed.1644842271.git.wangyunjian@huawei.com> (raw)
In-Reply-To: <cover.1644842271.git.wangyunjian@huawei.com>

When iavf_security_ctx_destroy() is cleaning up, it does not correctly
set the security_ctx variable to NULL, which will lead to wild pointer.

Fixes: 6bc987ecb860 ("net/iavf: support IPsec inline crypto")
Cc: stable@dpdk.org
